President Trump slammed Sadiq Khan on Saturday.

President Trump on Saturday once again slammed Sadiq Khan, the mayor of London. 
Trump shared a post from conservative British commentator Katie Hopkins who had criticized the Metropolitan Police for losing "control of London streets" and "apparently...of their twitter account" after it appeared the official police Twitter account was hacked, notes the Guardian.
Trump added the comment: "With the incompetent Mayor of London, you will never have safe streets!" 
Khan has been a prominent critic of Trump and the president has repeatedly attacked him.
During his UK visit last month, Trump told reporters that Khan "hurts the people of this great country."
